Why is a chain-of-custody type record useful?

Answer and explanation

Correct answer: To document sample identity, transfer, and the persons handling it

A chain-of-custody record documents the sample’s identity, who received or transferred it, when this happened, and its storage details. This helps maintain correct identification and reliability of the sample. Producing many DNA copies is the role of PCR, not of a record. Exam tip: If a question asks about the sequence of sample transfer and responsibility, choose chain of custody.
